Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460262, here are decompositions:

89 + 31460173 = 31460262
199 + 31460063 = 31460262
263 + 31459999 = 31460262
269 + 31459993 = 31460262
313 + 31459949 = 31460262
331 + 31459931 = 31460262
409 + 31459853 = 31460262
433 + 31459829 = 31460262

Showing the first eight; more decompositions exist.
